FRANK B. COOK, OF CHICAGO, ILLINOIS.

GUY-CLAMP.

To all'whom it concern:

Be it known that I, FRANK B. 0001:, a citizen of the United States of America, residing at Chicago, in the county of Cook and-State .of Illinois,. have invented a new and useful Guy-Clamp, of which the following is a specification, reference being had to the accompan ing drawings, illustrating same.

' y invention relates to clamps for holding any kind of strands or ropes and clamping same so as to secure twopieoes'of the strands or ro es thereinand hold same against longitudinal movement 'due to tensional stresses put on the strands 'or-ropes tending to pull them apart.

The principal objects of my invention are to provide a clamp which has increased holding power on the strands or ropes; over clamps heretofore made; to provide a clampin which but one aw portion is used instead of the two jaw portions generally used; to

customa to provide two jaw portions with grooves t erein in which grooves the strands or ropes are clam ed between the said jaw portions. In sue a clamdp there are two Law portions required besi es the necessary olts for clamping the jaw portions together.

In the clamp of my present invention I provide but one jaw portion and form it in the sha e of a trough and then provide wedge-s aped bolts extending through the bottom -of the trough to wedge in between the strands or ropes and Wedge the latter out 'into recesses formed in the sides of the trough. WVith this construction the cost 'of manufacture is greatly cheapened and the holding power is greatly increased by the wedge-shaped bolts which can be easily tightened up by nuts on the bottom side of the trough so as to put great pressure on the strands or ropes to wedge them in place in the recesses in the troug In the drawings illustrating the referredform of my invention, Figure 1 is a ront elevation-of a clamp embodying the features of Specification of Letters Patent. Application filed' liay 11, 1997. Serial No: 373,139.

the invention witha portion of one of the clamping bolts shown in cross-section taken on line y y of Fig. 2; Fig, 2 is a transverse cross-sectional View of the clamp shown in Fig. 1, taken on line 90 a: of Fig. 1, with the clamping bolt shown in elevation; Fig. 3 is a front elevation of another form of clamp embodying the features of the invention, with the clamping bolts removed; and Fig. 4 is an end elevation of the portion shown in Fig. 3. Like characters refer to like parts in the several figures.

The body portion 1 of the clam is made of a piece of metal, preferably s eet-metal, formed into a trough-like shape with the side portions bulged out as at2 2. Betweeneach 1pair of bulged-outportions 2 2 is rovided a ole 3 through the bottom of tie trough, through which a clamping bolt 4 extends. The portion 1 is made strong enough to resist considerable pressure tending to force .75

the side portions outward. If desired the bulged-out portions 2 2 may extend clean across the bottom portion of the trough-like portion 1, as shown in Figs. v3 and 4, as'wellasat the sides of the trough-like portion. Each clamping bolt 4 isprovided with a Wedge-shaped head adapted to lie between the strands or ropes 5 5 so as towedge the latter out against the sides of the trough-like portion and into the recesses 6 6 formed by the bulged-out portions 2 2. Eachwedging face 7 of each bolt 4 is preferably semicylindrical in form, as sl iown in Fig. 2 and by li'nes S 8 of Fig. 1, so as to provide a smooth hearing surface for the strands or ropes 5 5 and not indent or injure the latter when they are wedged out into the recesses 6 6. Each bolt tion 9 which serves to keep the stramsor ropes 5 5 from coming clear out of the trough when the bolts 4 4 are loosened. slightly. The inner surface 6 of each recess in the sides of the trough-like portion is scribed from c as a center, with a radius 2, and each semicircular element of the scmicylindrical surface 7 of each clamping bolt 4 is scribed with a radius equal to half the diameter of bolt 4.

c is located in a plane containing the longitudinal axis of bolt -l and extending at right angles to the length of the clamp, away from the said axis of bolt 4. If a bolt 4 be turned in the direction of arrow 0 as shown in Fig; 1, each one of the said elements would be ro-
